To rent a certain meeting room, a college charges a reservation fee of $32 and an additional fee of $7.70 per hour. The math
club wants to spend less than $62.80 on renting the meeting room.
What are the possible amounts of time for which they could rent the meeting room?
User for the number of hours the meeting room is rented, and solve your inequality for I.

32 + 30 = ≤4

$62.80 = r of ≤4

Step-by-step explanation:

62.80-32  =  30.80

= total - reservation fee = spending for hour rent.

=$30.80

30.80/7.50 = 4 hrs maximum with $0.80 left over.

So we say 32 + ≤4 as ≤ means equal to or less than.

168

step-by-step explanation:

i am pretty sure that the answer is 168

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
